What characteristic appearance is noted in the artery affected by Fibromuscular Dysplasia?

The characteristic appearance associated with Fibromuscular Dysplasia is the "beaded appearance." This refers to a specific pattern seen on angiographic imaging, where alternating stenosis (narrowing) and aneurysm (bulging) create a beads-on-a-string effect along the length of the affected artery, often observed in the renal arteries.

Fibromuscular Dysplasia often affects young women and presents with symptoms related to renal artery stenosis, which can lead to secondary hypertension. The beaded appearance is primarily due to the underlying pathology affecting the medial layer of the arterial wall, leading to alternating segments of diseased and normal vessel segments.

The other options do not accurately describe the typical imaging findings associated with Fibromuscular Dysplasia, which is clearly distinguished by its beaded pattern. The accordion appearance usually refers to a different pathological process, spindle shape is often associated with aneurysms or other vascular malformations, and a stenotic appearance simply refers to narrowing without the characteristic beading of Fibromuscular Dysplasia. Understanding these different descriptions helps in correctly identifying the conditions during diagnostic imaging.
